we using finagle stack , taught of adding zipkin tracing our micro-services. i able see our tracing happening parent finishes before child. i have opened issue here: https://github.com/openzipkin/docker-zipkin/issues/100 any appreciated. i recording wrong annotation i.e client instead of server. just simple change did trick. trace.traceservice("function1","test") sample working zipkin example: https://gist.github.com/akhilj876/3e38757c28d43924f296dd2d147c0bd9#file-zipkintracing_example-l34

given polygon s , point p lies outside s, imagine ant can follow straight line towards or away p. for shapes (fig. 1), there choice of p such ant can move unobstructed in @ least 1 of 2 possibilities: towards (t) p, or away (a) it. condition corresponds ray cast p intersecting perimeter of s 0 or 2 times. however, same shape (fig. 2) there may points lead blocked (b) regions, ant bump polygon whichever direction tries move in. yet other shapes (fig. 3) there may no choice of p leads no blocked regions. having blocked regions corresponds rays cast p intersect perimeter of s more 2 times. is there algorithm determines whether p exists satisfies condition given polygon s? if such points exist, can determine region contains them? find concave corners of polygon obstacle. each corner, extend 2 edges infinitely. sector between these 2 rays, , (as nico schertler pointed out) point-reflected region of sector, define point must obstacle not hide corner form point's rays...

lets have simple python code this: num1 = input() num2 = input() res = sum(num1,num2) as per requirements, should able convert above code(that got input user) in such way, should able supply inputs predefined file. how ? , once add code, above works. if add input below "num3=input()", should raise error eoferror: eof when reading line. how raise error ? num1 = input() num2 = input() num3 = input() res = sum(num1,num2) please let me know questions. well far know there's no way tell pythons input function read stdin. without rewriting code use file objects, redirect file stdin. send eof @ end of file , raise error you're expecting. for example run: python script.py < file.in or if have shebang on first line of file , you've made executable: ./script.py < file.in this assuming you're running linux based or posix shell.
